Advanced land windsurfing riders are able to perform technical freestyle tricks similarly seen in other extreme sports [ citation needed ] such as windsurfing, skateboarding and snowboarding .
An NMR tube is a thin glass walled tube used to contain samples in nuclear magnetic resonance spectroscopy. Typically NMR tubes come in 5 mm diameters but 10 mm and 3 mm samples are known. Typically NMR tubes come in 5 mm diameters but 10 mm and 3 mm samples are known.
RS:X is a windsurfing class selected by the ISAF [1] to replace the Mistral One Design Class for the 2008 Summer Olympics. The discipline has similarities to Formula Windsurfing - mainly in that the equipment used was designed to allow windsurfing in low and moderate wind conditions with good performance. [2]

The TWT is an elongated vacuum tube with an electron gun (a heated cathode that emits electrons) at one end. A voltage applied across the cathode and anode accelerates the electrons towards the far end of the tube, and an external magnetic field around the tube focuses the electrons into a beam. At the other end of the tube the electrons strike ...
